: First did a dry run then I the AMZER 1800mAh for the EVO. So far it's in first place for being the biggest ripoff on the gallon. First place.
August 5th: Received Carl's AMZER 1800mAh for EVO, doing a dry run discharge now, hopefully get some data for you tomorrow morning.
July 28th: Finished Carl's Seidio 3500mAh for EVO 4G. Seems the Seidios all rate at 81% of their claim.
July 6th: Completed round one of EVO stock (John Doward). Got the coveted Amzer 1800 and a Seidio 3500, both EVO, en route thanks to Carl Willi.
June 12th: Completed first run of a Mugen 3200mAh for the Hero. Both disappointing and unsurprising. Most cost ineffective battery I've tested.
June 11th: Jasper and Dan's batteries on the way back to them. Thanks again. Hey, Mugen 3200 for Hero and EVO 4G stock on their way! Another update, just received that Mugen 3200, charging now.
June 10th: Completed testing for a no name Hero battery and the stock Incredible battery with the EVO 4G stock on its way. Nice. Returning those batteries to my man Dan and my other man Jasper.
June 9th: Seems a seller I linked may be committing fraud. Please read
June 7th: First test complete of an oversized no name Hero battery, second one in progress.
April 26th: Got some press
. And a little more
April 15th: Hoo-F'ing-ray, we have a winner, Wade's HTC 2150mAh clocks in exactly at 2150! high five, HTC!
April 14th: Taking the HTC 2150mAh for a spin right now. Finally! Thank you Deathmonkey!April 12th: Rotohammer's Seidio 1600mAh for the N1 has arrived, charging. Exact dimensions as OEM, wish I had a scale.
April 9th: In a continued effort to outdo himself Rotohammer just ordered a 2400mAh-rated Cameron Sino, on its way to me. Lucky I got his attention. Extremely helpful. Thanks.
April 8th: N1 Seidio 1600mAh should show up today, thanks to Rotohammer.
April 3rd: Finished N1 Seidio 3200mAh, five runs. Learned that it's rated slightly more honestly than Mugen (not saying much) but is the most expensive battery per tested amp hour. Still, highest capacity. I got a new and fast and really badass server and now have a our own forum which you can fire up at forum.batteryboss.org
. Finished the new Andida for the TP2, pretty weak, but for some of you the price may be right.
March 30th: Completed dry run of a Seidio 3200mAh for the N1. Not fantastic but Seidio has taken the lead against Mugen in honesty.
March 29th: Mugen "engineer" responds (see table). Rotohammer's Seidio arrived, charging now baby, yeah! Should be very interesting. Thanks Roto.
March 27th: Shawn's OEM a fake (but a well performing fake). Activity building in the Nexus One thread
. Mugen sent me an exchange for Jeremy's and it sucks even more.
March 20th: Just ran the first test of the Nexus One's OEM, not bad.
March 18th: Just ordered a Google Nexus One. I got an extra battery so the first thing I'm using this for is to prepare a battery for testing. Need to figure out if it has different voltage cutoffs, need to figure out how to present the data and what to do with my site, .. hmmm.
March 16th: Mugen wants me to send me another battery to test, I agreed and mailed them back Jeremy's battery. Also mailed Sean/Telek his OEM 1500mAh. Thank you both fellas. Also DeathmonkeyGTX offered to sponsor a test of the HTC 2150mAh -- thank you!
March 13th: Finished no name #2 3600mAh (2466mAh :P). In search of voltage cutoffs for Touch Pro/Fuze, please help.
March 12th: Mugen has expressed interest in sending me another battery to test, I expressed willingness. And to you I express curiosity into which device to expand the testing.
March 8th:Finished round two of no name #2 and fake OEM #2. Waiting on another ebay OEM to verify authenticity and a fresh Andida courtesy of my main man Shawn Martell.
March 7th:Added intriguing head to head chart matches.
March 6th:Completed a few more including fresh standard legit OEM, also discovered two counterfeits
March 2nd: Completed no name #1, cheapest per mAh so far. Dropped Jason's battery off in the mail as promised.
Feb 28th: Completed tests of the Seidio, mailing it to jasonweaver.
Feb 27th: Just received Seidio 1750mAh from jasonweaver in addition to 1500mAh no name ebay cheapo. Nice.
Feb 27th: Mugen 1800mAh testing completed, table updated. Thank you very much jcr916 who bought the battery and had it shipped to me, now I'm going to mail it to him.
Feb 22nd: Thank you jasonweaver and jcr916 who are hooking me up with a barely-used Seidio and a brand new Mugen 1800mAh
respectively. Those test results should be interesting as from what I've gathered those two brands have the best reputation and are priced accordingly so let's see if they deserve it.
Telek and I just laid down some dough for five more batteries this weekend. So I'll have a lot of testing to do shortly. Stay tuned for the results!
Batteries I would like to test next so PM me if you want to help.
New and used batteries welcome.
Pricey worth it. Really want to test this one. *En route*
- Same model as AT&T but cheaper, doesn't come with door. *En route (same battery)*
- Found five favorable/neutral reports.
A new Seidio 1750mAh
- Tested a used one already but need data on a fresh battery.

Tips and other reflections:
AT&T people, beware that if you order a battery that requires a deeper back cover but is for the Touch Pro2 and not the AT&T Tilt 2 that the cover may not have a hole for the PTT button nor may it latch on. Maybe you can burn one through with a hot screwdriver or you could just crazy glue. Beware of the usual dangers of ebay obviously, only use sellers with high ratings and consider buying straight from the company's website or Amazon or a name you've heard of. I have found over two counterfeits from sellers with high ratings. Read your phone's warranty before using a third party battery. Get the return policy before you buy.
If you do get burnt with a counterfeit OEM, immediately give negative feedback using language like "counterfeit" and email the seller requesting both immediate restitution and that they remove their listings of that particular battery or at the least any reference in the listing to the battery being either an OEM or giving an OEM-like serial number, anything misleading, and in return offer to neutralize negative feedback. Reporting fraud to ebay is up to you but I would take those steps first. It's a longshot but the information we really want from the dealer is their supplier but so far I haven't been able to get any of them to cough that information up. If you're not sure if the thing's a counterfeit and want to find out, send it to me to test.
I am using the West Mountain Radio
CBA III (Computerized Battery Analyzer
) which you can buy along with some toys from these guys
for $149. I bought something else from them, didn't like it and they offered to shave the cost of the thing I didn't want off the price of the CBA III without even asking me to return it. Good people. The CBA III is the most accurate and reliable device we could find for these testing purposes and we spent many hours arriving at the final testing procedure. No corners cut. There is no indication whatsoever that the results it's produced are inaccurate, certainly not relative to each other given its consistency. All testing procedures were identical including the current of 250mA, starting voltage and bottom cutoff (4.14V and 3.5V respectively, the top and bottom cutoffs of the Touch Pro2, which I use to charge the batteries with original HTC wall charger). The 250mA current may be a little high and won't produce as flattering a result versus a 100mA current, but it's both a normal current we burn when we're doing stuff on the phone, it keeps each of the three tests inside six hours usually and most importantly we use that current on every single test of every single battery so this is a standardized test. Finally the OEMs get 95% of their claimed rating on this current so we believe that that current is the sweet spot to supply you with information to use to buy your next battery.
